If you just need Scala Play for some quick testing/demo of Scala code, even the Scala Play Starter Example is too heavy. It has a lot of example code that is not needed and too much security for something to be run and accessed only locally.

Here is how to trim down the Scala Play Starter Example. First is the conf/application.conf file. All that is needed for the whole file is:

Specifically, you can delete the /count and /message routes, and then add whatever routes you need for web services (like /mywebservice above).

In the app directory:

rm -rf filters

rm -rf services

rm Module.scala

rm controllers/AyncController.scala

rm controllers/CountController.scala

rm views/main.scala.html

rm views/welcome.scala.html

And then in views/index.scala.html you can just delete all the code therein and write your own regular HTML and not bother with the Twirl template language if you don't need it.

Finally, you'll need to create controllers/MyWebServiceController.scala. You can use HomeController.scala as a template and add in import play.api.libs.json._ to gain access to the Play JSON APIs for parsing and generating JSON.
